How To Fix R7845 - Choose a reference characteristic for InfoCube non-cumulative values

SAP Error Message - Details

• Message type: E = Error

• Message class: R7 - BW: Data basis

• Message number: 845

• Message text: Choose a reference characteristic for InfoCube non-cumulative values

What causes this issue?

You chose non-cumulative values in the InfoCube.
For a non-cumulative value, it is required that a mutual reference
characteristic for time aggregation be determined, that defines the
granularity (degree of detail), in which the non-cumulative values are
managed. This (time) reference characteristic is valid for <zh>all</>
non-cumulative values of the InfoCube and must, therefore, be the
"smallest" time characteristic in the InfoCube, in which the
non-cumulative values can be managed.
Examples
The InfoCube contains warehouse non-cumulative values as well as the
time characteristics 'calender month' and 'calender year'.
In this case, define the InfoObject calendar month (0CALMONTH) as a
reference characteristic for the time-based aggregation.
The InfoCube contains warehouse non-cumulative values as well as the
time characteristics 'calender week' and 'calender month'.
Here you must firstly include the time characteristic 'calender day' in
the InfoCube, since 'calender week' is not the "smallest" unit of
'calender month'. Then define the InfoObject 'calender day' (0CALDAY)
as a reference characteristic for the time-based aggregation.

• What is the cause and solution for SAP error message R7845 - Choose a reference characteristic for InfoCube non-cumulative values ?

  The SAP error message R7845, which states "Choose a reference characteristic for InfoCube non-cumulative values," typically occurs in the context of SAP BW (Business Warehouse) when working with InfoCubes that contain non-cumulative key figures. This error indicates that the system requires a reference characteristic to properly handle the non-cumulative values.
  Cause:
  The error arises when you are trying to define or manipulate non-cumulative key figures in an InfoCube without specifying a reference characteristic. Non-cumulative key figures are those that do not accumulate over time, such as stock levels or balances, and they require a reference characteristic to determine how the data should be aggregated or reported.
  Solution:
  To resolve this error, you need to specify a reference characteristic for the non-cumulative key figures in your InfoCube. Here are the steps to do this:
  
  
  Open the InfoCube in the Data Warehousing Workbench (RSA1):
  
  Navigate to the InfoCube that is causing the error.
  
  
  
  Edit the InfoCube:
  
  Go to the "Modeling" section and select the InfoCube you want to modify.
  
  
  
  Define Non-Cumulative Key Figures:
  
  In the key figure settings, identify the non-cumulative key figures that are causing the issue.
  For each non-cumulative key figure, you need to specify a reference characteristic. This is typically a time-related characteristic (like a calendar year, month, or day) or another relevant characteristic that can provide context for the non-cumulative data.
  
  
  
  Save and Activate:
  
  After specifying the reference characteristic, save your changes and activate the InfoCube.
  
  
  
  Test the Changes:
  
  Run a query or data load to ensure that the error has been resolved and that the non-cumulative key figures are functioning as expected.
  
  
  
  Related Information:
  
  Non-Cumulative Key Figures: These are key figures that do not accumulate over time. Examples include stock levels, balances, or any measure that represents a snapshot rather than a total over a period.
  Reference Characteristics: These are characteristics that provide context for how non-cumulative key figures should be interpreted. They are essential for proper aggregation and reporting.
  SAP BW Documentation: For more detailed information, refer to the official SAP BW documentation or help resources, which provide guidelines on modeling InfoCubes and handling key figures.
  
  By following these steps and understanding the context of the error, you should be able to resolve the R7845 error effectively.
